我已经在我的机器上安装了centOS 7,在过去的4到5个月里我一直在使用它,它运转良好。但几天前,由于断电(不恰当的关闭),我的机器发生了一些不好的事情。现在,当我启动系统时,它会在开始时给我这个消息。
XFS (dm-0): Internal error XFS_WAIT_CORRUPTED at line 1600 of file fs/xfs/libxfs/xfs_alloc.c. Caller xfs_free_extent+0xf9/0x130 [xfs]
XFS (dm-0): Failed to recover EFIs
带有结束错误消息

这个问题是可以解决的
请指导如何做上述任何一个来解决我的问题。

编辑:1我使用live-cd运行xfs_repair,输出是
sudo xfs_repair -v /dev/dm-0
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

在我的例子中,下面的命令起了作用。
sudo xfs_repair -v -L /dev/dm-0
电源中断后,我的节点未能启动,并得到了“未能装入/sysroot”的错误,并进入了紧急模式。
挂载和卸载失败了,所以继续使用-L
选项运行,这再次帮助我的节点启动。

听起来你需要运行XFS修理。断电一定使文件系统处于糟糕的状态。

你可以做一些XFS的修复..。
你应该运行xfs_repair吗?因为如果挂载失败并且日志包含脏日志,那么xfs_repair就不会运行,所以我们被迫使用(-L)选项,但是它的描述说(-L)会破坏文件系统。
如果xfs安装成功,即使在这种情况下访问某些文件也会导致IO输入/输出错误。
它为xfs_repair推荐了以下用法,以便您不会遇到以下问题:成功挂载、->、->、运行xfs_repair ->挂载失败->、xfs_repair -> xfs_repair失败->最后xfs_repair -L ->挂载
添加上述挂载+ xfs_repair过程使文件系统稳定
